Thank you for providing the stack trace. We are looking into the issue and will follow up with you as we learn more. In the meantime, are you able to check if you have a whitespace in front of the XML declaration? The `Caused by: org.xml.sax.SAXParseException: Content is not allowed in prolog.` error is typically thrown by the Java XML parser when data is encountered before the `<?xml...` declaration.

Please feel free to update us with any further information you think maybe useful.
